The purpose of the HF-Drive Trapping Field Generator is to create a sinus-shaped output voltage at
high amplitudes and high frequencies, which can be used to store ions in a Paul Trap, or to run a RFQ
(radio frequency quadrupole) structure for trapping and guiding ions or other electrically charged
particles. Unlike power rf generators, the outputs are designed to drive purely capacitive loads, like
electrical electrodes. The device is housed in a standard 19-inch rack-mount case.

This devices feature a fast-turn-on/off capability to capture
ions in flight. Other common RF drives usually require a certain amount of time to build up the nominal
output voltage since they are based on a resonant voltage transformation. In contrast the RF drive HF-D
series consists of broadband devices which allow for instant turn-on and fast turn-off of the AC output
voltage. The devices are housed in a standard 19-inch rack-mount case.

Our new QUAD 1-10 rotating wall drive is designed to create a rotating dipole or quadrupole electrical
field inside a Penning Ion Trap. The resulting electrodynamical "rotating wall" enables fast
compression of big ion clouds after loaded into the trap. The QUAD 1-10
represents a tool to handle a wide range of ions/plasma rotation frequencies with respect to this novel
application.

Picture: The QUAD 1-5b rotating wall drive is intended to create an
electric rotating dipole or quadrupole field inside a Penning Ion Trap. It's e.g. in use at the
University of Mainz, Department of NuclearChemistry,
AG Nörtershäuser.

The QUAD 1-5b rotating wall drive is a Precision Wideband Phase Shifter in combination
with output amplifiers, dedicated for compression of non-neutral plasmas in Ion
Traps. It provides 4 phase shifted outputs with up to 20Vpp Amplitude.
It operates in a wide frequency range from 100kHz to 5MHz. Small
mismatches of amplitude and phase are provided over the entire frequency range.

Drives for FAIMS Setups

Model RF-FAIMS 1.7

Picture: RF drive amplifier for FAIMS setups

The purpose of the RF FAIMS drive is to create a rectangular high voltage signal, suited to
apply the FAIMS (high-field asymmetric waveform ion mobility spectrometry) method for
ion separation in the gas phase. The device essentially works as an amplifier: A rectangular
5V (TTL-style) signal is applied at the input (fixed 5V amplitude), which may vary in
frequency and duty cycle. A corresponding high-voltage signal is created and presented at the
output.
